"at times" using "open with" shows many duplicate entries....reboot fixes it for a while..

 

I'm still trying to determine what is triggering this.

 

Any idea? Anyone see this in 10.8? I couldn't find anything searching the forums.

    I am not familiar with all the causes of this phenomenon, but it happens to me from time to time, and I know why it is for me. I work with "clone" images all the time with dev work. When a clone is mounted alongside booting into  the main volume, Launch Services, which keeps track of applications used to open certain file types, "sees" the other application files on the mounted clone volume, and adds them to the database, resulting in the apparent duplication of "open with" entries.

     

    Resetting the 'Open With' menu will remove duplicates and ghost applications (ones you have deleted) from the list. You reset the 'Open With' menu by rebuilding the Launch Services database your Mac maintains. There are multiple ways to rebuild the Launch Services database, including third-party system utilities like Cocktail and Onyx.

     

    If you don't own a system utility that can rebuild the Launch Services database, don't worry; you can perform the rebuild yourself using Terminal.

     

    Using Terminal to Rebuild the Launch Services Database:

     

    Launch Terminal, located at /Applications/ Utilities/.

     

    For OS X 10.5.x and later, enter the following at the Terminal prompt:

     

    /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.fram ework/Support/lsregister -kill -r -domain local -domain system -domain user

     

    ----------------

     

    I don't know wjhy it is happening for you, but rebuilding the database will at least reset things to normal. The question to ask is whether you have other mounted volumes, say from other systems on your network, that contain Mac Apps.

     

    I have also found a way to keep it from happening (in certain cases, for my dev work). When I create a clone, I also create what is called a "fstab" file entry, in the fstab file. This entry prevents named drives from auto-mounting. So, if I boot to a clone, my main volume on my internal SSD won't mount. Hence, no extraneous Launch Services database entries will created on the clone drive. If however, I boot to my main SSD, and then mount a clone, I don't use any fstab entries on the main SSD. This just means I have to periodically rebuild the Launch Services database. It is way too much trouble keeping fstab entries for all my clone drives on my main SSD. I only use the fstab method on the clones themselves.

    Thanks, I'll try your workaround. I've never had this occur before, but now it seems to every few days.

     

    At any rate, thanks for the work-around it will save rebooting...

     

    BTW: I happened to back-up the MBP last night and the BU drive has 4-clones on it...Interesting...however, I wonder why I haven't run into this before.

     

    Thanks again!!!

    I'll bet a buck that it is those clones that are causing the duplicate entries. You can minimize the problems if you immediately eject those drives, as soon as they are auto-mounted when you physically connect.

    Apps on other volumes shouldn't cause multiple entries in "Open With" unless they are different versions of the application. i.e. Abode CS4, Adobe CS 5.

     

    Try this syntax for the Terminal command...

    (be sure to copy the entire line it's a scroll)

     

     

           
    Code:
           
    /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user

     

    Then press return. Wait until terminal returns to the command line. Quit Terminal. After that, log out and back in or restart. Let us know

     

     

    Or, use the free utiltiy OnyX to do the same via gui

    These two articles may be of interest to you, if you continue to keep those clones around on a physical drive that is mounted on boot.

    Just so you know, fstab files can be more easily made, without error, by using a program called TinkerTool System (not regular TinkerTool). Just be aware that TinkerTool System is somewhat advanced tweaking software, not the harmless version they have for consumers (TinkerTool)

    I wish they wouldn't, but they do. It is a reproducable problem using clone images that I routinely observe.

     

    BTW, did you not notice the post above where I have answered the question in the same manner? (Terminal Solution)

    I have 3 connected drives with 8 volumes with clones of my system and when I use my "Open With", I have only 1 instance of each. As I said, it shouldn't be an issue.

     

    The reason I added the code is because our syntax differs.

    You should get the Solved for the post, if it works.

    When I run:

     

    /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.fram ework/Support/lsregister -kill -r -domain local -domain system -domain user

     

    ...on my MacBook Pro, running OS X - Mountain Lion, I get the following error:

     

    No such file or directory

  • 9. Re: "open with" duplicate entries

    Is there something different that has to happen, to remove duplicate entries from the "Open With" menu, under OS X, Mountain Lion?

  • 10. Re: "open with" duplicate entries

    Use the code I posted above copy the entire line, that way there are no line breaks. The syntax is important.

  • 11. Re: "open with" duplicate entries

    @macjack -

     

    I did a COPY/PASTE of your code, two or three times now. Each time, I got the same error.

     

    This time, I expanded the window, so that when I did a PASTE of your code, it didn't wrap, in the terminal screen. This time, it worked!

     

    Weird, huh?

    Yes.

    Either way, the issue is resolved now!

    Just relaunch Finder (control+option+click on Finder icon in the Dock) it will work. and dont have to logout or restart.
